Abstract
Beaches have many values to Pacific island communities, for protection
of the land from inundation, as well as community fishing, and tourism attractions.
However, beach erosion is prevalent on many coasts, due to both natural and
human causes. Coastal protection structures such as seawalls are expensive and
can cause negative impacts, such as erosion to adjacent coastlines. Ecosystembased
adaptation integrates biodiversity conservation and ecosystem services, and
engages natural ecosystem processes to provide alternative low-cost solutions to
beach erosion. Adapting well-known dune rehabilitation techniques to narrow
Pacific island beaches, beach ecosystem-based adaptation techniques include
beach access control fencing and gateways, and tree, shrub and ground vine planting.
Defined access pathways allow people to access the beach, and facilitate natural
recovery of trampled vegetation. These beach management tools are in
combination with local community capacity building, and engagement in maintenance
and monitoring, which fosters reduction of impacts. Communities use
locally available materials, and traditional expertise in the uses of matting and
fencing. Use of beach ecosystem-based adaptation can increase the resilience of
beaches to climate change and climate variability, and provide alternative softengineering
approaches that are both low cost and can be effectively applied by
local communities.
